HEADLIGHT.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed September 19, 1907. Serial No. 393,625.

To all whom it may concern: 7

Be it known that I, RICHARD H. WELLEs, a citizen of the United States, residing at Kenosha, county of Kenosha, State of Visconsin, have invented certain new and useful Im rovements in Headlights, of which the f0 owing is a specification.

This invention relates to improvements in head lights for automobiles.

Among the salient objects of the invention are to provide a construction which presents as fares practicable a smooth exterior surface substantially free from protruding screws or rivets, so that it may be more readily polished and at the same time presents a more finished appearance to provide a construction in whic the union members which'receive the securing rivets or screws are substantially concealed within the interior of the head light shell; to provide a construction which can be readily assembled or taken apart; and in general to provide an improved construction of the character referred to. y

The invent-ion will be readily understood from the following description reference bein had to the accompanying drawings in whic Fi ure 1 shows a longitudinal vertical sectionzil view of my improved head light, parts being broken away to show the details of construction. Fig. 2-is a cross-section taken through lines 2-2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a cross-section taken through lines 3-3 of Fig. 1.

'Fig. 4 is an enlarged detail view showing the a manner of securing the end wall to the main body of the shell.

Referring to the drawings, 1 designates as a whole thehead light comprising a cylindrical barrel or side body 2, :1 ;.:1vex end Wall 3; and a hinged flaring front member-4. The head light is also provided with the usual burner 6, air vent 7, reflector S, and front glass 01' crystal 9.

Therefiector is of sli htly less diameter than'the interior of the s iell and it is necessary that it be situated and supported atthe proper focal distance from the burner. It is also desirable that the end' wall be outwardly convex in order to give a more finished effect,

and that the reflector be spaced away from the shell to lessen the liability of breakage.

To this end I provide a combined oining ring reflector seat 10, which takes the form of an a confining flange 11 which fits within an annular shoulder 12 formed in therear end wall 3. The outer periphery of the ring 10 is bent radially outward at 13 and then forwardl at right angles thereto to form a cylin ric clamping extension 13 which fits snugly over the rear end of the side body 2. The edge of the extension 13 is formed into an outturned bead l3", c-rim ed over and interlocked with the end wal 3; the latter being provided at its periphery with a right angled extension 14 engaged by the head. The reflector is confined in its seat in the seat rin 10 by means of a confining ring 17. I It will be noted that the periphery of the reflector is sha ed to form an inwardly converging shou der 18 and the ring 17 is clamped against this shoulder. To this end the ring 17 is provided at its outer or lar er periphery with a radial flange 19 which ts against the corresponding portion 13 of the ring 10 when the arts are in assembled position. Upon the ack side of the ring 10 are soldered a plurality of nuts 20 which are threaded and arranged in register with aper- 17, the latter are clamped together by suitable screws 24 inserted through said parts and into the nuts.

Heretofore it has been the practice to secure the end wall to the main body of the shell by uniting the parts together by rivets or screws protruding through both the end wall and the main body. In order to obviate the necessity of such a. construction and as an important feature of my device I provide for detachably uniting the side member 2 and end wall 3 by brackets arranged-within. the shell of the headlight. To this end a plurality of right-angled brackets 23 are secured to the inner wall of the sidebody 2 and so arranged as to register with alternate ones of the nuts 20. Each of these brackets 23 is suitably apert-uredfor the reception of a confining screw 24. The end wa l 3 together with the reflector may now be secured to the main body of the shell by slipping the extension 13" of the ring 10 over the rear end'of the side body and inserting screws through the brackets 23, flanges 19 and 13 and nuts 20.

end wall and reflector may first be assembled and then secured to the side body without resorting to the use of external rivets, bolts or screws passing through the end wall.

Referring now to the front end of the head light, the flarin fiont 4 is suitably hinged to the front end 0 the side body 2 in the usual manner. The outer end of this flaring extension is contracted to form an annular shoulder 25, the inner edge of which is bent inwardly at right angles to the shoulder portions to form anabutting flange 26 against which the crystal or front glass rests. This glass is adapted to fit over the open end of the-flaring front 4 and is'secured in position against the flange 26 by means of an annular confining ring designated as a whole'27. The outer margin of the ring is bent radially inward to form a confining, flange 28. To provide space for a packing ring and also to give the structure a more finished appearance the ring is extended slightly beyond the glass before it is bent inwardly to form the flange 28 and its extreme margin is turned inwardly at right angles, at 29, to meet the face of the glass. Between the glass and the flange 28 is an asbestos packing 30 which serves to keep out dirt and moisture. The cylindrio part of the confining ring telescopes overthe outer end of the flaring front 4 and terminates in an annular bead 31 which adds to the finished appearance of the device.

In order to secure the confining ring to the front extension 4 and as an important feature of'my construction, I provide a series of connecting brackets 32 riveted to the inner side of the ring 27 as shown'clearly in Fig.3 and eachprovided with a threaded aperture 33. The ring is secured to the extension 4 by inserting suitable ssrews 34 through the shoulder 25 and brackets 32. It is of course obvious that these screws may be inserted from the inside of the shell by swinging open the extension 4 on its hinges.

From the foregping description it will be seen that I accomplish the several objects of the invention and produce a headlight casing of extremely neat and finished appearance, devoid of many of the external rivets and projections which have heretofore been found indispensable, and furthermore so constructed that the reflector may be removed bodily with the end closure of the casing by simply releasing the latter, thereby avoiding much of the dangerincident to removing the reflector from its seat, and also avoiding the necessity of separately removing these parts.

It will be obvious that the details of construction may be somewhat modified without departing fromthe invention.

I claim as my invention: 1. In a headlight, tllGCOIIlblHfitlOIl of a side body member, an end closure member having telescopic engagement with the side body, and means uniting said parts comprising a sheet metal joining ring interfolded with the out-turned margin of one of said members and ext-ending radially within the shell, internal radially extending projections on the other member extending adjacent to and in overlapping relation to said ring, and screw bolts extending through the ring and internal projections.
